read more may be inserted to maintain airway patency during bag-mask ventilation. If available, an oropharyngeal airway How To Insert an Oropharyngeal Airway Oropharyngeal airways are rigid intraoral devices that conform to the tongue and displace it away from the posterior pharyngeal wall, thereby restoring pharyngeal airway patency. Lay rescuers may provide compressions-only CPR or, if trained to do so, may give rescue breaths delivered mouth-to-mouth (for adults, adolescents, and children) or combined mouth-to-mouth-and-nose (for infants). read more should be started as early as possible, but bag-valve-mask ventilation should not delay initiation of compressions or defibrillation. When health care professionals provide CPR, bag-valve-mask ventilation Bag-Valve-Mask Devices If no spontaneous respiration occurs after airway opening and no respiratory devices are available, rescue breathing (mouth-to-mask or mouth-to-barrier device) is started mouth-to-mouth ventilation. If the initial rhythm is pulseless electrical activity or asystole, an initial dose of epinephrine 1 mg IV/IO (intravenous/intraosseous) should be administered as soon as possible after recognition of cardiac arrest. If the cardiac arrest is witnessed and a defibrillator is on the scene, a person in VF or VT should be immediately defibrillated, with compressions immediately resumed after shock is delivered early defibrillation may promptly convert VF or pulseless VT to a perfusing rhythm. read more (VT) is given an unsynchronized shock (see also Defibrillation Defibrillation Cardiopulmonary resuscitation (CPR) is an organized, sequential response to cardiac arrest, including Recognition of absent breathing and circulation Basic life support with chest compressions. Symptoms depend on duration and vary from none to palpitations to hemodynamic collapse and death. read more (VF) or pulseless ventricular tachycardia Ventricular Tachycardia (VT) Ventricular tachycardia is ≥ 3 consecutive ventricular beats at a rate ≥ 120 beats/minute. It causes immediate syncope and death within minutes. Remember, push hard and push fast! You should deliver 30 chest compressions without pause.When a defibrillator (manual or automated) becomes available, a person in ventricular fibrillation Ventricular Fibrillation (VF) Ventricular fibrillation causes uncoordinated quivering of the ventricle with no useful contractions. Allow the chest to fully recoil (expand) between compressions to allow the heart to fill with blood.Provide at least 100 compressions per minute. You should compress the chest straight down about 1 ½ inches.With the infant lying flat on their back on a firm surface, place two fingers just below the nipples (lower half of the sternum).Not allowing the chest to fully recoil results in less blood flow with every compression. You should do what is necessary to compress the chest about 2 inches. One hand is not better than two or vice versa. If necessary, use two hands to compress the chest. You should provide at least 100 compressions per minute. You should compress the chest about 2 inches. In a small child, it may only be necessary to use one hand. With the victim lying flat on their back on a firm surface, place the heel of the dominant hand on the sternum between the nipples (lower half of the sternum). Place your hands in the same place as you would when giving chest compressions to an adult.Not allowing the chest to fully recoil results in less blood flow with every compression, which means that the brain will not get enough oxygen. You should compress the chest at least 2 inches. Your shoulders should be positioned directly over your hands, forming a straight line from shoulders to wrists. Straighten your arms so that your elbows are locked. Place the heel of your non-dominant hand on top of your first hand and lace the fingers of both hands together.With the adult victim lying flat on their back on a firm surface, place the heel of the dominant hand on the sternum between the nipples (lower half of the sternum).Injuring the victim is unlikely, but is a much better outcome than death. It is a common fear of many rescuers to not push hard enough on the victim’s chest because they are afraid of hurting the victim.
